  • 3-phase inverter module, motor driving apparatus using the same, and inverter integrated circuit package
    Patent number: 8027183
    Abstract: A 3-phase inverter module is provided, which includes first and second U-phase switching elements connected in series to each other to constitute a U-phase inverter, first and second V-phase switching elements connected in series to each other to constitute a V-phase inverter, first and second W-phase switching elements connected in series to each other to constitute a W-phase inverter, a U-phase high voltage integrated circuit for generating a control signal for controlling the U-phase inverter according to a U-phase input signal, which has a fault-out terminal for the U-phase, a V-phase high voltage integrated circuit for generating a control signal for controlling the V-phase inverter according to a V-phase input signal, which has a fault-out terminal for the V-phase, and a W-phase high voltage integrated circuit for generating a control signal for controlling the W-phase inverter according to a W-phase input signal, which has a fault-out terminal for the W-phase.
